CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. Ser. No. 10/442,477, filed May 21, 2003, and claims priority of prior Provisional Application No. 60/382,247 filed in the United States of America on May 21, 2002.

TECHNICAL FIELD OF THE INVENTION

The invention relates to portable power generating devices and more particularly to portable devices for converting potential energy from flowing water, water current, blowing air or air current to mechanical and/or electrical energy.

DESCRIPTION OF THE RELATED ART

Hydropower energy is the mechanical and/or electrical energy converted from potential energy in moving water or water current. Hydroelectric power is the electrical power converted from the potential energy in, among other things, moving water or water current. It is important to note that a mechanical function is usually required to convert potential energy in moving water or water current to hydroelectric power.

A shortcoming of many existing hydropower or hydroelectric (hereinafter individually and collectively referred to as “hydropower”) systems are the costs associated with constructing these massive structures. These structures include, but are not limited to, dams, intakes, scrolls, bends, diffusers, or other permanent structures (hereinafter individually and collectively referred to as “permanent structures”). The purpose of these permanent structures is to manipulate the flow of water and to capture or convert the potential energy from moving water or water currents to useful mechanical and/or electrical energy. These permanent structures have numerous negative consequences.

Permanent structures are very expensive to construct and maintain and the costs associated with decommissioning these permanent structures are very high. Large areas of land and waterways are occupied by these large, intrusive, and foreign permanent structures. Unique natural wildlife is sacrificed to construct these permanent structures.

Moreover, these permanent structures seriously alter the hydrology of impounded waterways creating flood hazards and safety concerns to surrounding areas. In Oregon, Washington, and Idaho, a multi-million dollar salmon fishery was destroyed resulting in unemployment for thousands of people.

Environmental groups have created fierce opposition to the construction of new permanent structures and have lobbied for the removal of existing permanent structures. Environmentalists have protested against these permanent structures because of their impact to the environment.

The present invention is directed to overcoming one or more of the problems set forth above.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 illustrates a single drum portable power generating device, generally designated 1. The portable power generating device 1 is for use in conjunction with a moving fluid, such as water. Arrow “B” shows a surface of the moving fluid and arrow “A” shows which direction the fluid is moving in. The single drum portable power generating device 1 has a single drum 19, which is cylindrical and has buoyancy. The single drum portable power generating device 1 has vanes 2 operatively mounted around the outer circumference thereon. The vanes 2 extend outwardly from the outer circumference of the single drum 19 of the single drum portable power generating device 1. In all embodiments discussed hereinafter, the vanes can be of various configurations and designs such as straight, curved, angled, cupped, ribbed, concave, rigid, flexible, steel, plastic or any other similar structure. The configuration and design of the vanes 2 are dependent upon many factors, such as, obtaining the maximum possible potential energy from the moving water or current. In the preferred embodiment for the single drum portable power generating 1, the vanes 2 are angled against current or towards the water flow as illustrated in FIG. 1A. In other embodiments, the angle and length of the vanes 2 are varied. For example, the angle of the vanes 2 may be transverse to the point of contacts with the single drum 19 of the single drum portable power generating device 1. The length, positioning and angle of the vanes 2 determine the amount of potential energy from moving water or water current that will be captured and converted to mechanical and/or electrical energy explained hereinafter. An axle 3 is operatively mounted through the center of the single drum 19 of the single drum portable power generating device 1. A frame 4 is operatively connected to the axle 3 at an at least one first end 5 of the frame 4. The axle 3 is rotatably mounted at the at least one first end 5 of the frame 4. The axle 3 is able to rotate freely at the at least one first end 5. The frame 4 receives the axle 3 on each side of the single drum 19 in the preferred embodiment as shown in FIG. 1B. The frame 4 receives the axle 3 on each side of the single drum 19 in an alternative embodiment as shown in FIG. 1C. The frame 4 has at least one anchoring yoke 11 at an at least one second end 12 of the frame 4. The at least one anchoring yoke 11 is used to anchor the single drum portable power generating device 1.

At least one anchoring cable 13 is connected to at least one anchoring yoke 11 and an anchoring device (not shown) to preclude the single drum portable power generating device 1 from being carried away by the current or flowing water. The at least one anchoring cable 13 is a cable, rope, chain or any similar device. The at least one gear 6 is operatively mounted juxtaposed to a first side 8 of the single drum 19. At least one gear 6 rotates as the single drum 19 rotates. As moving water contacts the vanes 2, the single drum 19, the at least one gear 6 and the axle 3 rotate in the depicted embodiment. In an alternative embodiment, the axle 3 is bearing mounted and does not rotate with the single drum 19. At least one transition gear 7 is operatively mounted on the frame 4. The at least one transition gear 7 interacts with the at least one gear 6. As the at least one gear 6 rotates, the at least one transition gear 7 rotates. In an alternative embodiment, a second of at least one gear 6 is located on a second side (not shown) of the single drum 19 or opposite the first side 8. In an alternative embodiment, a number of at least one transition gears 7 interact with each other and/or the at least one gear 6 as shown in FIG. 1. Obviously if the at least one gear 6 is placed on the first side 8 and the second side, or both sides of the single drum 19, a second or second set of at least one transition gear 7 would be required for both sides. At least one power conversion unit 9 is operatively mounted to the frame 4. The power conversion unit 9 is an electrical generator, hydraulic pump, air pump, or water pump. The at least one power conversion unit 9 has at least one power conversion unit gear 10. The at least one power conversion unit 9 is used to convert the rotational movement from the power conversion unit gear 10 to electrical, mechanical or some other form of useful and useable energy. The at least one power conversion unit gear 10 is operatively mounted to the at least one power conversion unit 9 and interacts with the at least one transition gear 7. If the at least one gear 6 is placed on the first side 8 and the second side, or both sides of the single drum 19, the at least one power conversion unit 9 and at least one power conversion unit gear 10 is placed on the second side of the single drum 19 also.

The single drum portable power generating device 1 is anchored to the anchoring device via the at least one anchoring cable 13 and the at least one anchoring yoke 11 so that the single drum portable power generating device 1 is positioned in a current or moving water. The current or moving water contacts the vanes 2 thereby causing the single drum 19 to rotate. As the single drum 19 rotates, the at least one gear 6 and the axle 3 rotate in the depicted embodiment. However, in other embodiments the axle 3 is bearing mounted and does not rotate with the single drum 19. The at least one gear 6 operatively communicates with the at least one transition gear 7. The at least one transition gear 7 operatively communicates to or rotates the power conversion unit gear 10. The at least one power conversion unit gear 10 is rotated by the at least one transition gear 7 and operatively communicates with the at least one power conversion unit 9. As the at least one power conversion unit gear 10 rotates, the at least one power conversion unit 9 converts the rotational energy to electrical, mechanical or some other form of useful and useable energy.

FIG. 2 illustrates a multiple drum portable power generating device 20. The multiple drum portable power generating device 20 is similar to the single drum portable power generating device 1 but includes multiple drums 21, at least one collective 22 and various other components described hereinafter. The multiple portable power generating device 20 has the multiple drums 21, which are cylindrical and have buoyancy. The multiple drums 21 have vanes 26 operatively mounted around the outer circumference thereon. The vanes 26 extend outwardly from the outer circumference of the multiple drums 21 of the multiple portable power generating device 20. In the preferred embodiment, the vanes 26 are angled against current or towards the water flow as illustrated in FIG. 1A. In other embodiments, the angle and length of the vanes 26 are varied. For example, the angle of the vanes 26 may be transverse to the point of contacts with the multiple drums 21. The length, positioning and angle of the vanes 26 determine the amount of potential energy from moving water or water current that will be captured and converted to mechanical and/or electrical energy explained hereinafter. The multiple drums 21 are operatively connected to multiple frames 23 on each end via multiple axles 24.

The multiple axles 24 are operatively mounted through the center of the multiple drums 21. The multiple axles 24 are rotatably mounted to the multiple frames 23. Multiple gears 25 are operatively mounted juxtaposed to a first side 27 of the multiple drums 21 of the multiple drum portable power generating device 20. The multiple gears 25 rotate as the multiple drums 21 rotate because of the at least one collective 22 connection. As moving water contacts the vanes 26, the multiple drums 21 and multiple gears 25 of the multiple portable power generating device 20 rotate thereby rotating the multiple axles 24 because the multiple axles 24 are able to rotate freely at the ends in contact with the frame 23.

The multiple gears 25 are operatively connected to at least one power conversion unit gear 28 via the at least one collective 22. Multiple transition gears 29 are operatively connected to the multiple frames 23 and are used to transfer the rotation from the multiple gears 25 to the power conversion unit gear 28 via the collective 22. As the multiple gears 25 rotate, the conversion 22 is actuated or moved thereby moving the multiple transition gears 29 and the at least one power conversion unit gear 28. In the preferred embodiment, the collective 22 is a chain. The at least one power conversion unit gear 28 is operatively connected to at least one power conversion unit 30. The power conversion unit 30 is an electrical generator, hydraulic pump, air pump, or water pump. The at least one power conversion unit 30 is used to convert the rotational movement to electrical, mechanical or some other form of useful and useable energy. It is obvious to those skilled in the art that the at least one power conversion unit 30, the at least one power conversion unit gear 28 and associated components could be placed on each end of the multiple drums 21 of the portable power generating device 20. At least one anchoring yoke 31 is located at one end of and is operatively connected to the multiple frames 23. The at least one anchoring yoke 31 is used to anchor the multiple drum portable power generating device 20.

At least one anchoring cable (not shown) is connected to the at least one anchoring yoke 31 and an anchoring device (not shown) to preclude the multiple drum portable power generating device 20 from being carried away by the current or flowing water. The anchoring cable is a cable, rope, chain or any similar device.

The multiple drum portable power generating device 20 is anchored to the anchoring device via the at least one anchoring cable and the at least one anchoring yoke 31 so that the multiple drum portable power generating device 20 is positioned in a current or moving water. The current or moving water contacts the multiple vanes 26 thereby causing the multiple drums 21 to rotate. As the multiple drums 21 rotate, the multiple gears 25 and multiple axles 24 rotate such that the multiple gears 25 rotate, in this example, clockwise causing the at least one collective 22 to move thereby rotating the multiple transition gears 29 counterclockwise. In other examples, the multiple axles 24 are each bearing mounted such that they do no rotate with the multiple drums 21. The multiple gears 25, multiple transition gears 29, and at least one collective 22 operatively communicate with the power conversion unit gear 28. The at least one power conversion unit gear 28 is rotated and operatively communicates with the at least one power conversion unit 30. As the at least one power conversion unit gear 28 rotates, the at least one power conversion unit 30 converts the rotational energy to electrical, mechanical or some other form of useful and useable energy.

FIG. 3 illustrates a spiral portable power generating device 40 used for converting potential energy from flowing water or water current to mechanical and/or electrical energy. The spiral portable power generating device 40 has at least one drum 41. The at least one drum 41 is cylindrical and has buoyancy. In alternative embodiments, the at least one drum 41 is a cylindrical tube or axle of variable length having buoyancy. The at least one drum 41 has vanes 42 operatively mounted around the outer circumference thereon. The vanes 42 extend outwardly from the outer circumference of the multiple drums 41 of the spiral portable power generating device 40. However unlike the FIGS. 1 and 2, the vanes 42 do not extend along the longitudinal of the at least one drum 41.

Rather, the vanes 42 are substantially transverse to the at least one drum 41. The thickness section 43 of the vanes 42 substantially face the current or moving water. The vanes 42 are angled so that the current or moving water will cause the vanes 42 and the at least one drum 41 to rotate. The at least one drum 41 is operatively mounted on a collective output 44. As the at least one drum 41 rotates, the collective output 44 rotates. The collective output 44 is operatively connected to a collective (not shown). For all embodiments contained herein, the collective is any arrangement of axles, gears, pulleys, chains, belts sprockets, shafts, pumps, plates, clutches or cables that transfers rotational force from any axle or collective output. Specific embodiments illustrated herein are the best mode operation and not meant to be limiting to said illustration. The collective transfers the rotational movement to at least one power conversion unit (not shown), wherein the at least one power conversion unit converts the rotational movement to electrical, mechanical or some other form of useful and useable energy. The power conversion unit is an electrical generator, hydraulic pump, air pump, or water pump. The spiral portable power generating device 40 is anchored by at least one anchoring cable (not shown) attached to an anchoring device (not shown).

The spiral portable power generating device 40 is anchored to the anchoring device via the at least one anchoring cable or the collective, and the at least one anchoring yoke so that the spiral portable power generating device 40 is positioned in a current or moving water. The current or moving water contacts the vanes 42 thereby causing the vanes 42 and the at least one drum 41 to rotate. As the at least one drum 41 rotates, the collective output 44 rotates. The collective output 44 operatively communicates with the collective. The collective operatively communicates to the at least one power conversion unit, and the at least one power conversion unit converts the rotational energy to electrical, mechanical or some other form of useful and useable energy.

FIGS. 4 and 5 illustrate a fan turbine portable power generating device 50 used for converting potential energy from flowing water or water current to mechanical and/or electrical energy. Moreover, when the fan turbine portable power generating device 50 is in an upright position, it is used for converting potential energy from blowing wind or air current to mechanical and/or electrical energy. The fan turbine portable power generating device 50 is mounted on a plurality of pontoons 55. The plurality of pontoons 55 are substantially cylindrical and have buoyancy. In alternative embodiments, a plurality of drums, axles or similar devices having buoyancy are used in place of the plurality of pontoons 55. The plurality of pontoons 55 have a plurality of anchoring yokes 76. Referring now to FIG. 4, the plurality of anchoring yokes 76 are used to anchor the fan turbine portable power generating device 50. Anchoring cables (not shown) are connected to the plurality of anchoring yokes 76 and an anchoring device (not shown) to preclude the fan turbine portable power generating device 50 from being carried away by the water current, flowing water, blowing wind or air current. The anchoring cables are cables, ropes, chains or any similar devices. At least one cable and winch 63 connect the plurality of pontoons 55. The at least one cable and winch 63 control the depth of a plurality of vanes 72 that will be submerged in the water. The at least one cable and winch 63 is used to vertically raise and lower the plurality of vanes 72 so that the depth of submersion of the plurality of vanes 72 can be controlled. Front struts 64 have bottom ends 65 rotatably mounted on the plurality of pontoons 55 and angled inwardly and front top ends 66 of the front struts 64 are rotatably connected together such that when the cable and winch 63 are moved so too does the angle of the front struts 64. Rear struts 67 have rear bottom ends 68 rotatably mounted on the plurality of pontoons 55 and angled inwardly and rear top ends 69 of the rear struts 67 are rotatably connected together such that when the cable and winch 63 are moved so to does the angle of the rear struts 67. An axle 51 is rotationally and operatively mounted from the top ends 66 of the front struts 64 to the top ends 69 of the rear struts 67. A collective gear 73 is operatively mounted around the axle 51.

A power conversion unit gear 74 is operatively mounted to a power conversion unit 75. The power conversion unit 75 is an electrical generator, hydraulic pump, air pump, or water pump. As the axle 51 and the collective gear 73 rotate, the collective gear 73 interacts and rotates the power conversion unit gear 74. A nose cone 71 is operatively mounted between the front struts 64 and the rear struts 67. The plurality of vanes 72 are operatively mounted around the circumference of the axle 51 and operatively mounted to the nose cone 71. The plurality of vanes 72 are arranged to rotate when acted on by water current, moving water, blowing wind or air current. When the plurality of vanes 72 rotate, the axle 51, the collective gear 73 and power conversion unit gear 74 rotate. The power conversion unit 75 receives and converts the rotational energy from the power conversion unit gear 74 to electrical, mechanical or some other form of useful and useable energy.

FIG. 5 illustrate a close up of a front view of the fan turbine portable power generating device 50 shown in FIG. 4 without the nose cone 71 attached thereto. The axle 51 is rotatably mounted to at least one middle section 53. The at least one middle section 53 is operatively connected to the front struts 64 and/or rear struts 67. The plurality of vanes 72 are operatively mounted to a circumference of the axle 51. The plurality of vanes 72 are angled so that the water current, moving water, blowing wind or moving air causes the plurality of vanes 72 to rotate. At least one space 57 is provided between each of the plurality of vanes 72. The plurality of vanes 72 are transverse to the water current, moving water, blowing wind or moving air.

The depth of submersion of the plurality of vanes 72 of the fan turbine portable power generating device 50 in the water is adjustable.

In an alternative embodiment, the fan turbine portable power generating device 50 is placed in the upright position, wherein the plurality of the vanes 72 are not submerged in the water and the fan turbine portable power generating device 50 is used for converting potential energy from blowing wind or air current to mechanical and/or electrical energy. The upright position is desirable when water surfaces freeze not allowing submersion of the plurality of the vanes 72 therein.

In the preferred embodiment, a cable and winch 63 are used to control the depth of submersion of the plurality of the vanes 72 of the fan turbine portable power generating device 50 in the water. The cable and winch 63 are used to move the plurality of pontoons 55 toward and away from each other thereby controlling the depth of submersion of the plurality of vanes 72 of the fan turbine portable power generating device 50 in the water. The cable and winch 63 are for illustration purposes, and are not meant to be limiting. Other embodiments are able to perform the same function and are known by those skilled in the art.

Referring once again to FIG. 4, the fan turbine portable power generating device 50 is anchored to the anchoring device via the anchoring cables and the anchoring yokes 76 so that the fan turbine portable power generating device 50 is positioned on a body of water with the plurality of vanes 72 submerged in the water facing the direction of the water current or flowing water or when the plurality of vanes 72 are completely removed from the water, in the direction of the blowing wind or moving air. The water current, flowing water, blowing wind or moving air contacts and causes the plurality of vanes 72 to rotate. As the plurality of vanes 72 rotate, the axle 51 and the collective gear 73 rotate. As the collective gear 73 rotates, it interacts with the power conversion unit gear 74 causing it to rotate. The power conversion unit gear 74 operatively communicates with the power conversion unit 75. As the power conversion unit gear 74 rotates, the power conversion unit 75 converts the rotational energy to electrical, mechanical or some other form of useful and useable energy.

FIG. 6 illustrates a below surface fan turbine portable power generating device 80 used for converting potential energy from flowing water or water current to mechanical and/or electrical energy. The below water fan turbine portable power generating device 80 has an axle 81. The axle 81 is rotatably mounted to a housing 83. Vanes 84 are operatively mounted to a circumference of the axle 81. The vanes 84 are angled so that the when the current or moving water contacts the vanes 84, it causes the vanes 84 to rotate. Space 85 is provided between each of the vanes 84. The vanes 84 are transverse to the current or moving water. The below water fan turbine portable power generating device 80 is anchored to the bottom surface of a body of water, such as a channel, river, stream or the like, by spikes 82.

The wave generating device 122 has a flat or curved member 130, which is placed upstream of the portable power generating device. The flat or curved member 130 angled upward or transverse to the direction of the water's current and below the surface of the water.

The flat or curved member 130 directs the flowing water upward thereby causing a standing wave 124. The standing wave 124 rises above the water surface and contacts the wave generating device 122 with more force than the “normal current.” The vanes 2 of the portable power generating device receive the standing wave 124. The standing wave 124 created by the wave generating device 122 increases the kinetic energy of the water's flowing current by adding the weight of the falling water in the collapsing wave 124 to the speed of the current driving the vanes 2 of the portable power generating device. The wave generating device 122 is operatively mounted to the frame 4 of the portable power generating device by at least one strut 123.

FIGS. 10 a and 10 b illustrate a water directing device 125 as described in Disclosure Document 494831, Jun. 4, 2001, which is hereby incorporated by reference and attached hereto. The water directing device 125 is used to increase the power of the flowing water delivered into any one of the previously discussed portable power generating devices. The water directing device 125 has a flat or curved support 131, which is placed upstream from the portable power generating device. The flat or curved support 131 extends from above to below the normal surface elevation of the flowing water. The flat or curved support 131 is preferable operatively mounted to both sides of the portable power generating device. The flat or curved support 131 of the water directing device 125 are angled inward (toward the vanes 2) and increases the speed and volume of the current moving toward the water directing device 125. The flat or curved support 131 of the water directing device 125 is attached to the frame 4 of the portable power generating device 1 by at least one strut 126.

This Water Directing Device disclosed in FIG. 11 is placed in front, below and to the sides of the aforementioned Power Generating Devices and by doing so, increases the kinetic power of the flowing water delivered into the Power Generating Devices by several ways.

First, the amount of water interacting with the collectors on the Power Generating Device is increased in volume and speed.

Second, the increase in the volume and speed of this flowing water increases the efficiency of any Wave Generating Device that may be deployed in conjunction with the Power Generating Device.

Third, stabilizes the Power Generating Device in its operational location within the flowing current of water.

The Wave Generating Device is placed in front of the aforementioned Power Generating Devices, and by doing so, a standing wave higher than the surface of the water is created. The creation of this standing wave increases the kinetic power of the flowing water delivered into the Power Generating Device by several ways.

First, the speed of the water flowing down the wave slope is increased due to the fact that the wave slope is at a steep angle relative to the surface of the water.

Second, this downward fall of water creates a gravitational weight force that increases the power delivered to the collectors on the Power Generating Device.

Third, the shape and flow characteristics of the standing wave smoothes out the delivery of water into the collectors on the Power Generating Device, thereby reducing drag and increasing the ability of the collectors to extract energy from the moving current of water.

In view of the foregoing, it will be seen that the several advantages of the invention are achieved and attained.
